I love it is open source and no account is needed. Also my data is not shared anywhere. As for features, I would love if I could add nutrients to track, like sugar, fiber, etc. Those values are present in the data so why not track them? Another feature I'm missing is adding notes to the activity/meal. This would be amazing for tracking elimination diets, where the user could add a note if the meal made him feel sick. If the app had those 2 features it would be 5* for me.

My issues of my last review have been resolved but now another issue has appeared: Adding system-provided meals (not custom meals) is now a horrendous experience; changes made to serving sizes or names are no longer saved, and non-custom meals are no longer pushed to the top of recently used items if they are recently used. Please revert back to the old system.

Great. But I would prefer to have more control over which nutrients I want to track specifically (eg. only fiber or cholesterol or vitamin D,...). Also I would like to be able to choose a diet (keto, Mediterranean,...) and then see how closely my logged food matches this diet and where it deviates. while adding a new food and switching between apps the keyboard sometimes disappears and only a black box remains.
